San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

What To Do With A Rat After It Is Caught
After successfully catching a rat, people are often faced with the issue of what to do next. There is more to removing rats in your home than just catching it. If you have caught a rat in your home, there are certain things you will have to consider before going ahead with any activity.
The first thing you will have to consider if you caught a live rat is whether to relocate the rat to somewhere far away from your home or kill it. Secondly, you will have to figure out the best way to handle the rat without having any close contact with it, so as not to put your health at risk. Lastly, you will have to make plans on how to thoroughly disinfect your home.
If you are sensitive to animals, the best way to handle this situation is to choose the humane way by relocating the rat somewhere far away from your home after catching it. But at the same time, you need to understand the fact that the rat might not survive in the new environment you intend to introduce it to. Rats are habitual and are usually accustomed to living in the environment they grow up in. When you relocate any rat you caught, it will find it difficult to feed in the new environment. In most cases, these rats don't usually survive more than a few days.
On the other hand, if you have decided to kill the rat after trapping it, it is best to kill it fast and quickly. The best way to do this is to use either a blunt object that is firm and heavy or use a fire weapon.
While doing all of these, you need to protect yourself as much as you can to avoid getting in contact with diseases and pathogens. To do this, wear a pair of gloves while handling the rat and dispose of them immediately after use.
